Relationship between observed and fitted relative growth rate (RGR, upper panels) and survival rate (lower panels) and shade (a,d), spatial drought (b,e) and inter-annual drought (c,f) of the abundant treelet Faramea occidentalis. Growth decreased significantly in deeper shade (a) and survival decreased significantly in drier sites (e, spatial drought) and years (f, inter-annual drought). Large dots represent mean observed growth or survival for ten shade or drought classes, each containing 10% of the individuals of the species (only six classes in (f), due to high abundance in one year). Lines show fitted growth and survival with increasing shade (a,d, orange), spatial drought (b,e, green) and inter-annual drought (c,f, blue), at mean values of the other independent variables. Solid and dotted lines indicate significant and non-significant responses, respectively. Lines whose colour differs from the large dots within each panel represent 1 SD increase in shade (orange), spatial drought (green) or inter-annual drought (blue). Figure S1 presents responses to shade and drought for all analysed species.
